Description
Highlights: • GO-PANIs/Epoxy nanocomposites were fabricated and analyzed. • GO-PANI composites improved the corrosion resistance of the epoxy coating. • GO-PANI I significantly improved the barrier/active performance of epoxy coating. - Abstract: Graphene oxide nanosheets were functionalized with polyaniline (PANI) nanofibers through three methods In method II the polymerization of aniline was done in the presence of sodium dodecyl sulfate as a surfactant and ammonium persulfate as an initiator. In method I the surfactant and in method III the initiator were eliminated during polymerization procedure. The morphology and chemistry of the nanosheets were characterized. Then, the GO/epoxy and GO-PANIs/epoxy nanocomposites were fabricated and their corrosion protection performance was studied on steel substrate by electrochemical impedance spectroscopy. Results revealed that GO-PANI remarkably improved the barrier performance and provided active inhibition for epoxy coating.
